Powerpoint animation

I have a powerpoint presentation/animation that I want to be viewed on a personal website. What is the easiest way to do this and what format should I convert it to? The presentation is not that large, perhaps half a meg max and it consists of about 50 slides automatically changing at a 1 second rate.

The fast transition time was set on purpose. It provides a simple animation, there is no text, just pictures. I would want it to run at this speed in whatever format it is converted to. There is no need for any user control as it is just a demo. The YouTube idea is not a bad one as I have links to YouTube videos already on my site. Just need to convert it.
